Hear the music, not the volume controller

Niles volume controls deliver sound to your speakers without getting in the way of the music. While lesser components add pops, clicks and static, Niles brings you pure enjoyment. Their premium-quality parts and construction ensure high-fidelity sound with amplifiers rated at up to 100 watts per channel of continuous power.

Great for systems large or small

These in-wall stereo volume controls offer intuitive operation for your multi-room audio system. The high-power, impedance-magnifying design lets you safely connect as many as eight controls and eight pairs of speakers to a typical receiver or amplifier without installing a speaker selector or any other type of protection device. The sliding control design provides an attractive, modern look.

If your amp's minimum impedance is 8 ohms, you can connect up to 8 pairs of 8-ohm speakers using these volume controls. If your amp's minimum impedance is 4 ohms, you can connect up to 16 pairs of 8 ohms speakers, or 8 pairs of 4 ohm speakers.

Product Highlights:

connect up to 8 pairs of 8-ohm speakers to a single stereo amplifier (requires 1 volume control per speaker pair)

Features

Overview: The SVC100K (FG01653) is a
high-power sliding stereo speaker volume control that connects between the speaker-level output of
an amplifier, speaker selector, or a Niles distribution hub and a pair
of speakers. It lets you adjust the volume of a pair of loudspeakers, just as a
light dimmer enables you to control the light. Premium-quality parts and construction ensure high-fidelity sound
with flat frequency response and 100 watts continuous power
handling. It is designed for indoor use only.

Four Colors: The SVC100K installs in-wall in a standard
single-gang junction box (J-box). The package includes a Decora faceplate and
slider insert in each of four colors: white, light almond, bone, and black.

Selectable Impedance Magnifying Circuit: A
universal impedance magnifying circuit enables the SVC100K to act as both a
stereo and an impedance magnifying volume control. You can magnify the speakers'
impedance by a factor of two, four, or eight, allowing you to connect up to
eight pairs of speakers to a single amplifier or receiver. A sliding switch on
the circuit board lets you set the impedance factor to 1x, 2x, 4x, or 8x.

12-Step Control: The slide switch gives you 12-step control,
and a total of 54dB maximum attenuation. The high-quality construction assures
you get pop-free switching between all steps.

Speaker Connectors:
The 2-piece screwless speaker connectors make installation quick and secure. Each
connector can accept up to 16-gauge wire.

Code Compliance:
The SVC100K is listed to comply with local building codes. You should check with
your local building official to ensure code compliance for your jurisdiction.

Installation
Considerations

Mounting: The SVC100K has a mounting depth of 2-9/16". When
installed, the unit extends 2-1/16" behind the sheetrock (assuming 1/2"-thick
sheetrock). A standard 18 cubic-inch or larger J-box is required.

Speaker Wire: The SVC100K will accept
stranded copper wire up to 16-gauge. Larger (lower gauge) wire is not
recommended, as it will not fit into the connectors. Solid-core, aluminum, or
"Romex" wire is not recommended. Most states require in-wall speaker
wire to have a specific "CL" fire rating.

Required Tools: To install the SVC100K,
you will need a Phillips screwdriver and wire stripper.

Quality counts

Quality makes a difference. I've had experience with sliders made on the cheap and they're frustrating to use. A slide is supposed to give you fine volume control, but if the parts don't fit together very well, then fine control just isn't there.

What impressed me most about the SVC100k is the quality of the construction. The controls slide easily, yet they remained in tight contact with the conductive strips. And they also stayed in place once I removed my hand. The lack of play in the slider ensures it will remain exactly where I want it.

And the four color options are most welcome. Sure, I could paint the outer plate, but it's better all around if I don't have to.
